ALVIN W. VAN DORSTON, OF SALEM, OREGON.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 314,496, dated March 24, 1885.

Application filed June 20, 1882.

T0 @ZZ whom t may concern:

Be it known that I, ALvIN W. VAN Dons- TON, residing at Salem, in the county of Marion and State of Oregon, have invented an In1- proved Automatic Self-Adjusting Car-Coupling, of which the following is a full, clear, and exact description.

This invention has relation to that class of car-couplings known as automatic or selfadjusting, and it consists of the mechanism hereinafter described, and fully pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of one end of a car with the coupler attached. Fig. 2 is a longitudinal vertical section of the draw-head and coupling mechanism. Fig. 3 is a perspective view of so much of the coupler as projects from the front of the car, looking from the rear. Fig. 4 is a detached View of the sliding jaws and coupling-bar. Figs. 5 and 6 are detached views of the slidingjaws; and Figs. 7, 8, and 9 are detached perspective views or" the coupling-levers.

m indicates the drawhead, which is provided in the interior, y y, with grooves g,above and below and near the mouth, for the reception of the jaws f. The walls o and a are for the reception of the actuating-levers Z, connected with the jaws fin the groove g crosswise of the draw-head m.

k indicates a rook-shaft, which is held in place by means of the braces t, secured tothe end of the car.

j indicates a lip, which is thrown back in a horizontal position by turning the rock-shaft k over when not in use and forward in a horizontal position for the purpose of operating the readjusting-lever r.

rlhe rock-shaft Zo is provided with a weight at one end and ahandle at the other, and horizontal with the lip j is the rod d, extending to the top of the cars for the purpose of operating the said rock-shaft 7c into or out of position, for the purpose of operating with the adjusting-lever r, and shifting the latch e to hold the weight angle-levers Z Z in an uncoupled position when not in use. The levers h h on each side of the car and lever o at the' top of the car are connected at w with the right-angle (No modell l levers Z by chains c, for the purpose of uncoupling the cars when coupled. The draw-head m is provided with the horizontal grooves g crosswise in the interior and near the outer endof the space .Q/,for the reciprocation of the jaws, reciprocating horizontally to and from each other by the action of the right-angle levers Z Z, and the adjusting-lever 'r is secured to the back wall, o, and under the right-angle lever Z, for the purpose of readj usting or locking the same, if desired, for coupling or uncoupling. The rubber block z is supported by the stud Q, passing through the front wall, a, and the said block e 'extends from the front wall, a, to and through the back wall, o, to the adj usting-lever r, for the purpose of holding said lever in position until thrown forward by coming in contact with the rockshaft 7c. l

lt will be observed that the stud x on one of the levers Z and the slot in the other lever are for the purpose of operating each other' when both are operated.

I n Fig. 3, S indicates a slotted stud having pinfholes and pins passing through the back and front walls, for holding said levers Zin contact with each other and in combination with the jaws f.

Having described my invention, what I claim is-n l. In adraw-head having thefrontand back walls, o and a, the slotted stud S, lever r, and movable latch e, the pinholes and pins passing through from the back wall, o, to the space, P', between the wall a and front end, the rubber block z, extending from the front wall, a, through the back wall, o, to the readjustinglever r, and the pin Q, for supporting the said rubber block e, as shown and described.

2. In a draw-head, the combination of the rubber block z with the readj'usting-lever r, in connection with the levers Z between the walls o and a, connecting with thejawsf, re ciprocating in the grooves f/,for the admission ofa connecting-bar,substantially as described.
